.ROW PLANTER.

I j Application iiled January 14, 1931. Serial No. $0 8,735.

This invention relates to a check row planter. More particularly, it relates to'the manner of mounting thecheck row shaft on such a planter.

In the use of check row planters, it is essential that seed discharging valves; which are operated by a check shaft extending transversely across the planter be actuated v at exactly the same time. In manufacturing provide a construction in'which adjustment may be made to correct the errors brought about by manufacturing inaccuracies and to provide for correcting the misadjustment brought about by normal wear on the planter arts. 7

p Another object is to provide a removable bearing for the check shaft, which may be readily replaced when it becomes worn sufficiently to affect the proper operation of the planter.

These and other objects, which will be apparent from the detailed description to follow, are accomplished by the construction and arrangementof the parts as shown in the 5 drawings, in which:

Figurel is a plan View of such portions of a planter as are necessary toillustrate the invention; i

Figure 2 is an enlarged detail view of the adjustable bearing which constitutes an essential element of the invention;

Figure 3 is a section taken on the line 3-3 of Figure 2;

Figure 4; is an end view-of. the construction shown in Figure 1, part of which is shown in section to illustrate'the discharge valve action; and 7 1 l Figures 5 and 6 are enlarged details of the removable and adjustable bearing.

The construction which constitutes this invention may be utilized in any conventional check row planter such as that illustrated in the drawings. Only a portion. of the planter frame :is shown;

The parallel barslO constitute'a portion of the planter frame. LA' check row head 11 of a conventional frame is mounted at each end on the bars 10. Thecheck rowhead con-i tains the usual wire guiding means wand 13 for holding the check wire in operative rela' tion with respect to the check fork 14, which is mounted on the rock shaft 15. ,Boots 16 extending downwardly. below the planter frame, are adapted tobe attached abov e 'the runner in-the usual manner. 'Seed hoppers 17 are suitably mounted on the planterfram'e to provide a seed supply "for the dispensing mechanisms operated there beneath and driven by the shaft 18. The seed is discharged through a delivery chute 19 onto a retaining Imember' 20. The member 20 is pivotally mounted with respect to the boot and is provided with-ca lever extension 21, by which it is operated. At the bottom of. the boot a discharge valve 22 is 'pivotallymounted and extends across thebottom of the boot in such'a manner as to beoperative to close or open said boot forlther discharge of seed therefrom. An a'ctuating link 23 is pivot ally connected to the valve '22 and to ra-link '24. The lever extension 21 is alsopivotedto the members 23 and 24 on 'thesame} axis; The link 24 "is pivotally connected? to a'lever arm 25, whichis-ri gidly mountedwon the rock shaft 15.- At each end ofcthe rock shaft 15.

adjustable bearings 26 are provided. :As shown in Figures 5 and 6,-these bearings :com-

prise an annularpor'tion'through whiich the sha ft\ 15 extends and laterally extending flanges. 27. i The flanges 27 extend fromi flat tened side portions of .the bearings. :The

surfaces; from which the flangestextend are ,1 parallel to provide'for vertical movement in the slots 28 formed in the Acheck heads. @Set head :in which 7 the 3101; is formed. Trans versely extending openings 30, are 'formed'in' abut the inner side of the portion of the cheek the bearing 26, considerably larger than the check shaft which passes therethrough. Bearing sleeves'31 having square holes therethrough corresponding in size and shape with the cross section of the check shaft, are fitted thereon and; are rotatably mounted in v the openings 80 in the bearings. Flanges 32 formed on the outer ends of the sleeves ,31

' abut the outer ends of the bearings and the checkforks '14 whereby longitudinal move ment of the check shaft and'the sleeves is prevented.

When a planter is first assembled in which this invention is embodied, the discharge valves 22 are timed by vertically adjusting V the-bearings 26. It will be understood that due to the construction of the linkage comprising the lever arm 25, the link 23', the lever extension; 21 and the link 24, any vertical dis placement of the axis of the check shaft 15 will alter the time of discharge of the valve 22, By position of an'adjustable bearing, as described, the planter when assembled may 2 be adjusted so that the valves 22 at each side of the planter discharge at exactly the same time. 2 c

When a planter has become worn in use,

particularly in the check shaft bearings, the

the rock shaft on the planter, whereby the time ofoperation of the discharging mechanisms may be altered.

4:. In a check row planter seed discharging mechanisms mountedon the planter, a rock shaft extending transversely of the planter provided with means for operation by a check wire, a pair of bearing means adjustably mounted on the planter for rotatably supporting the ends of said rock shaft, lever 7 arms carried-by said rock shaft at spaced positions thereon, and means connecting said lever arms with the seed discharging mecha nisms, whereby the adjustable bearing is effe'ctive for alteration of the time of operation of the discharging mechanisms,

. In testimony whereof I affixmy'signature.
